    Encrypting large amounts of data

    I have a datatable that has about 1000 rows of data that I need to encrypt.
    I have written the datatable out to XML and encrypted it using Rijndael and
    DES encryption. I have decrypted it and tied it back to a datagrid
    successfully. The purpose is to encrypt the data to go across the line for
    a web service. The question I have is--Is there a good way to encrypt a
    datatable using Rijndael or DES encryption that is quicker? Right now this
    method takes close to 10 minutes to encrypt the data table. That is just to
    long. I have suggested using a call back to notify the client when the
    webservice is done processing, but I need shorter times. Any thoughts,
    suggestions, code?

      There is no need to encrypt the data the way you are doing now...

      You can encrypt a web service call using SSL. Otherwise, load Web Service
      Enhancement and WS-Security contains the ability to encrypt web service
      messages at the message level.

          SSL is no faster, and in fact much slower since it has to encrypt the whole
          message not just the data table. WS-Security is not an option right now due
          to interactions with old Java Programs that have no support for WS-Security.

              Your current encryption takes 10 minutes!

              I'm sure IIS' SSL implementation is faster than 10 minutes ;-)
